DVD player. A DVD player is a device that plays discs produced under both the DVD-Video and DVD-Audio technical standards, two different and incompatible standards. Some manufacturers originally announced that DVD players would be available as early as the middle of 1996. These predictions were woefully optimistic.
Screen Options. Portable DVD players can have an LCD and/or LED screen attached to the actual player. LCD stands for liquid crystal display and projects images by using the light modulating crystals of liquid crystals. LED stands for light-emitting diode and acts as a semiconductor, emitting low-intensity light.
